I just hope it rolls out soonish. Cannot make use of my purchased track switch at the moment…this is such a weird thing to do: selling an item on your store that just “a few” users can use, without any hint

You bought before read the letters saying that for H2C release firmware is in Q2 2026. Not bambu fault…

The team is doing the final checks, and the final release should be available by the end of the week.
Once it is publish, I will make sure to announce it here too.
Thank you for all the help in testing and reporting the issues encountered!

To be fair, yes, “without a hint” is not correct, but it was just not really prominently placed 
It’s not that I am mad or searching for somebody to blame, the problem is just that I cannot use it, since I am also not able to install the beta firmware due to limited participants
So this is kind of a soft lock here.
before you release could you please remove the annoying behavior on using TPU? just let us use external spool on the right nozzle it shouldn’t be hard right… right???
U cannot use now, need to wait more a little time for final proper release.
Nobody wanna a bugger firmware for H2C because a quick release to all people that bought FTS before bought what they are buying in site descriptions.
It’s kind of scary to see how many people bought things without read.
With that said, bambu support already told us here that by the final of the week they will release firmware for everyone.
Have you reported this issue with a ticket during the testing phase?
If so, please let me know the ID via a private message so we can double check.
Thank you
It’s too bad that you can’t run the Filament Track Switch and the TPU Feed Assist (via the bypass port) at the same time … Once the FTS is installed, everything HAS to go through it - otherwise it just doesn’t work. That pretty much defeats the whole purpose of the TPU Assist, doesn’t it?
I really hope that this will be fixed in the firmware (if not now, then at least in the near future).

No, I didn’t report this because it looks like this is an “obviously unwelcomed feature” rather than “bug”, just like what @Dextera is describing, FTS requires everything to go through it, including TPU, which doesn’t make sense at all. This means that the TPU filament has to go through FTS and Buffer, creating huge potential of issues.
Which means that to print TPU+PLA support, you would need to:
- disconnect FTS
- disconnect ptfe tubes for toolhead
- disconnect ptfe tubes for AMSs
- reconnect ptfe tubes for AMSs directly to printer buffer
- reconnect AMSs for pla feeding
- reconnect ptfe tube for external loading of TPU.
- reconnect TPU feeder
…
And then after printing TPU you just reverse everything back…
And the bug that I reported got somewhat ignored, ticket number: US260513453001

Any feedback during the beta testing phase should be reported through a ticket, like mentioned in the first post. The team will directly get it and consider any changes.
Unfortunately, in such threads there is a lot of off-topic discussions and while I check it regularly, I might miss some details.
I will forward this to our team for their consideration.

Hi mate
Unfortunately you’re late to the party, as there was a moment on the website where it said the h2c was supported, which is when people began to buy, then it was later added that the software would allow it early June.
Hence why people are annoyed to a degree.

None of this surprises me. I know people who financed a home with an adjustable-rate mortgage and were genuinely shocked when their payment increased. You would think that the single largest purchase most people ever make would demand the most careful scrutiny of its terms yet it often doesn’t. These aren’t stupid people they simply come in with unrealistic expectations. I’d like to think that people visit forums like this one first to understand what a product and a company are actually about before committing to a purchase. Anyone who has spent even a modest amount of time in the real world or in communities like this one quickly learns that corporate communication tends toward the vague. I consider this from the start and make it a point to leave no stone unturned before buying. The more expensive the item, the more thorough my research. From that research, I have to weigh whether the potential hassle of a delayed or problematic delivery is worth the money spent. For me, $60 is simply not enough money justify the frustration especially after already purchasing the FTS. In a nutshell, research whatever your buying and set your expectations accordingly.

I just got my first AI nozzle clumping notification the other day on this firmware. It paused the print, yet everything looked pristine. I have never gotten error this before this firmware. It resumed just fine and didn’t notify me again. I’ve started enabling clump detection by probing in all my prints now.
Sorry, but what you’re describing should not be accepted. At the end of the day, we’re not talking about the little shop next door where you forgive some employee’s mistake because he or she is just so nice.
Bambu Lab is a company currently estimated to be making around a billion in revenue. This is not exactly a poor little company we need to feel sorry for.
As a customer, I need to be able to rely on what is stated in the store. The fact that they later added an extra note only proves that they messed this up in the first place. And when you mess up, you take responsibility for it, especially as a company with billion-level revenue.
It also doesn’t matter how expensive the product is. This is about the principle. I’m not even bothered that I had to read up on this first and then contact support, but that still doesn’t make it something people should just casually accept from a billion-dollar company.

I was hoping if the Bambu team can add a logic if external filament detected (TPU). The Filament Track Switch should in fact stay frozen with a default path line for the right nozzle. So whatever AMS connected to the Input-A feed will go out straight to Output-A feed and ignore the B path entirely since it is fed by TPU.
We should probably suggest this on a ticket. SupportAssis is just a forum mod I think.
Problem is that there is no detection. It can rely on a logic though, if there is filament in the toolhead but no detection from the switch or the buffer it then mean we’re using TPU. If no detection from the switch but detection from the buffer, it means we’re using external spool but that means we have an adapter between the switch and the printer to feed the external spool which will induce additionnal friction anytime the switch is used.
I would welcome an option in studio and in printer menu where you can disable the switch as required
That’s a perfect solution as well.
I thoght the easiest way would modify the slicer.
Let user can force filament with FTS go to a fixed nozzle.
Hello, I noticed you’re no longer accepting new names for the beta, but do you know if it’s still being rolled out? I’m registered for the beta and haven’t received it yet, even though the Filament Track Switch was delivered to me for the H2C. Thanks for your reply.
